Mechanical Properties and Flame retardancy of Polypropylene/Clay Nanocomposites |
| 초록 |
The ability for PP to be used as an engineering thermoplastic is still limited by its poor mechanical properites, in particular toughness(impact resistance) and stiffness(modulus). Therefore, it is expected that the simultaneous incorporation of an elastomeric phase(SEBS) and a rigid phase(organoclay) could lead to an attractive material with simultaneous enhancements in toughness and stiffness relative to the neat PP. The purpose of this study is to examine the mechanical properties and flame retardancy of PP reinfoced with an organoclay and toughened with an elastomer(SEBS) made by melt processing. To promote exfoliation of clay platelets in PP, PP-g-MA material is premixed with the organoclay prior to melt processing. The mechanical properties and flame retardancy of PP nanocomposite depend strongly on the change in the ratio of organoclay/PP-g-MA, PP/oragnoclay, and PP/SEBS. |
